error in read_nm_models when controlfile contains $PROB

[AndreasCalvagone]

Reading a controlstream only (i.e. no lst or ext available), throws an error when the Problem tag in the code is abbreviated as "$PROB".

The issue is in various lines of code that search for a string that starts with $PROB but is longer.
suggest to replace
stringr::str_detect(model, "^\\s*\\$PROB.+")

with

stringr::str_detect(model, "^\\s*\\$PROB")

@AndreasCalvagone thanks for reporting this. I implemented your suggestion in the development version, could you please check that it works on your example and re-open the issue if not?
